Cognitive enhancers work to boost brain function and mental clarity, often by improving blood flow to the brain, supporting neurotransmitter activity, or reducing oxidative stress. They are commonly used to enhance focus, memory, and overall cognitive performance. Examples include herbal nootropics like ginkgo (Ginkgo biloba), bacopa (Bacopa monnieri), and rhodiola (Rhodiola rosea), which are known for their ability to promote mental sharpness and resilience. Cognitive enhancers are beneficial for those seeking improved focus, productivity, or support for age-related cognitive decline.
